If you are on shared hosting, you NEED to have the administrator install ioncube at the server level, since user-based php.inis won't work since they are loaded after the server-wide php.ini.

The only other thing I can think of is the loader actually loaded on your server is 3.x and the plugin developer used ioncube version 7 to encode (which needs 4.x loaders)_________________http://ionvz.com

The Loader wizard is the way to go. For some shared hosts, such as godaddy, custom php.ini files are possible and that's the way to install, in others the host will add support, in others runtime install without a php.ini file is possible, and so on. The wizard also has a way to provide us with details in a ticket so that we can advise further._________________Community Admin
